I'm having the same problem with 'no programme information'. I have tried going to BBC 1 HD but unfortunately hasn't worked foe me.
I have cleared cookies and done manual as well as default retune. Switched off in wall, removed aerial and put back in, but still no luck.
I should be with Crystal P. transmitter although no way it shows in the TV.
I tried emailing Humax but it just comes back as non deliverable!
Thanks in advance.
